I have a Brother printer which every device in the house can use but suddenly the wife’s laptop cannot reach. It worked 2 days ago, nothing new installed or changed, but the printer remains unreachable for her.
Ping shows:
PING 192.168.1.9 (192.168.1.9) 56(84) bytes of data.
From 192.168.1.12 icmp_seq=1 Destination Host Unreachable
I went through every step here and read several posts like this and could finally add the printer in localhost:631 but the printer remains Host Unreachable.
This may be pointless but as I recall what seemed to magically solve my issue from long ago was to temporarily connect the computer via ethernet cable rather than wifi. After that, the misbehavior ended when trying to connect via wifi.
Worth a try since your wife’s laptop is portable enough.
How long has the printer been off for before someone tried printing to it again? If it’s WiFi connected there is a chance it received a new ip address.
I will admit I haven’t actually printed from CUPS or use a printer so I am just throwing general printer issues I’ve encountered out there as I usually try to map a MAC address to an ip for the printer when I can.
Does the printer still work for you with the same ip address on your PC?
@ArchieLinux anything is worth a try - we both work from a home office and this is not a good problem to have! Unfortunately, this did not work.
@_Six The printer is never off, always on though often in sleep mode and remains connected to wifi. It does work with the original ip address on 2 of my computers, my main which is on EOS like hers.
